Description

Technical Field

[0001] The utility model relates to the technical field of lithium batteries, and particularly relates to a laser welding fixture for battery tabs. Background Technique

[0002] Batteries are divided into positive and negative poles. The tabs are metal conductors that lead out the positive and negative poles from the battery core. Generally speaking, the ears at the positive and negative poles of the battery are the contact points during charge and discharge. When welding the battery tabs, a welding fixture is required to position the welding position of the tabs. Usually, the methods of visual inspection and reference objects are used, and the welding quality is judged based on the measurement results after welding.

[0003] Currently, the Chinese utility model with the publication number of CN218800091U discloses a lithium battery tab welding fixture, which includes a base. Both sides of the top of the base are fixedly provided with side plates. At the bottom of the inner sides of the two side plates, cylinders are fixedly installed. The movable ends of the two cylinders are fixedly provided with clamping seats. At the top between the two side plates, a mounting seat is fixedly provided. One end of the inner wall of the mounting seat is rotatably provided with a lead screw. The end of the lead screw away from the inner wall of the mounting seat extends to the outside and is fixedly connected with a turning handle. On both sides of the surface of the lead screw, sleeves are threadedly arranged. For the lithium battery tab welding fixture of the utility model, by rotating the turning handle, the lead screw is driven to rotate, and the two sleeves are driven to move towards or away from each other, so as to facilitate the adjustment of the positions of the two tabs. By pushing the two clamping seats towards or away from each other by the two cylinders, the distance between the two clamping seats is adjusted to match the tab welding of different models of lithium batteries, and the application range is wider.

[0004] Based on the retrieval of the above patent and the discovery of the equipment in the existing technology, although the above equipment can solve the problem that the existing welding fixture cannot match the tab welding of different models of lithium batteries during use, resulting in a narrow application range, during the use process, the device is not provided with a cooling structure, resulting in the surface temperature of the tabs being too high to be effectively cooled after the laser welding process of the tabs is completed, thereby reducing the welding efficiency of the battery tabs.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1 to 4 shown, a laser welding fixture for battery tabs provided by the present invention includes a base 1, an adjustment frame 2, a clamping frame 3, and a clamping seat 4. The adjustment frame 2 is fixedly installed on the top of the base 1. The clamping frame 3 is movably connected to both sides of the inner wall of the adjustment frame 2. The clamping seat 4 is fixedly connected to both sides of the inner wall of the base 1. A blower 5 is fixedly installed on the top of the adjustment frame 2. A hose 6 is arranged on the front side of the blower 5. The other end of the hose 6 is communicated with a cooling cover 7. A sliding plate 8 is fixedly connected to the outside of the clamping frame 3. An adjustment block 9 is movably connected to the inner wall of the sliding plate 8. A mounting plate 10 is fixedly installed on the outside of the adjustment block 9. The surface of the cooling cover 7 is movably connected to the inner wall of the mounting plate 10. An adjustment assembly 11 is fixedly connected to the top of the sliding plate 8. Limiting assemblies 12 are fixedly connected to both sides of the outside of the top of the mounting plate 10. A protection assembly 13 is fixedly connected to the bottom of the inner wall surface of the cooling cover 7.

[0024] Referring Figure 1 and Figure 2 , the adjustment assembly 11 includes a servo motor 111. The servo motor 111 is fixedly installed on the top of the sliding plate 8. The output end of the servo motor 111 is fixedly connected to a reciprocating screw 114. The bottom of the reciprocating screw 114 is movably connected to the bottom of the inner wall of the sliding plate 8 through a bearing. The surface of the reciprocating screw 114 is threadedly connected to the inner wall of the adjustment block 9.

[0025] As a technical optimization solution of the present invention, by setting the adjustment assembly 11, the servo motor 111 can effectively drive the reciprocating screw 114 to rotate, and then the reciprocating screw 114 drives the adjustment block 9 to adjust the position of the mounting plate 10, so as to facilitate adjusting the cooling cover 7 inside the mounting plate 10 to the precise required position.

[0026] Referring Figure 1 and Figure 3 , the limiting assembly 12 includes fixing plates 121. The fixing plates 121 are fixedly connected to both sides of the outside of the top of the mounting plate 10. A sliding rod 122 is fixedly connected to the inner side of the fixing plates 121. A limiting plate 123 is movably connected to the surface of the sliding rod 122. A spring 124 is sleeved on the surface of the sliding rod 122. One end of the spring 124 is fixedly connected to the inner side of the fixing plates 121. The other end of the spring 124 is fixedly connected to the outside of the limiting plate 123.

[0027] As a technical optimization solution of the present utility model, by setting the limiting component 12, the fixing plate 121 can effectively fix the sliding rod 122. The spring 124 on the surface of the sliding rod 122 pushes the limiting plate 123 to move inward, so that the inner side of the limiting plate 123 fits against the outer side of the cooling cover 7, thereby being able to limit the position of the cooling cover 7 and prevent the cooling cover 7 from shaking during cooling.

[0028] Reference Figure 1 And Figure 4 , the protection component 13 includes a protection frame 131, and the protection frame 131 is fixedly connected to the bottom of the inner wall surface of the mounting plate 10. A protection net 132 is fixedly connected to the inner wall of the protection frame 131.

[0029] As a technical optimization solution of the present utility model, by setting the protection component 13, the protection frame 131 can effectively fix the protection net 132. The protection net 132 can protect the bottom of the cooling cover 7, thereby preventing welding residues from splashing into the interior of the cooling cover 7 and causing blockage.

[0030] Reference Figure 1 And Figure 2 , both sides of the adjusting block 9 are movably inlaid with balls 14, and both sides of the inner wall of the sliding plate 8 are provided with chutes 15. The surface of the balls 14 is slidably connected to the inner wall of the chutes 15.

[0031] As a technical optimization solution of the present utility model, by setting the balls 14 and the chutes 15, when the adjusting block 9 moves, it can effectively drive the balls 14 to rotate, and the balls 14 rotate and move on the inner wall of the chutes 15, thereby improving the smoothness of the adjustment of the adjusting block 9 and preventing the adjusting block 9 from getting stuck when moving.

[0032] Reference Figure 1 And Figure 4 , a pull rod 16 is fixedly connected to the outer side of the limiting plate 123, and the pull rod 16 is arranged in a T shape.

[0033] As a technical optimization solution of the present utility model, by setting the pull rod 16, the T-shaped pull rod 16 can facilitate the user to pull the limiting plate 123 to move outward, so that the limiting plate 123 is separated from the cooling cover 7, facilitating the user to disassemble and maintain the cooling cover 7.

[0034] Reference Figure 1 , limiting rings 17 are fixedly connected to both sides of the front side of the adjusting frame 2, and the limiting rings 17 are sleeved on the surface of the hose 6.

[0035] As a technical optimization solution of the present utility model, by setting the limiting rings 17, the limiting rings 17 can effectively limit the position of the hose 6, thereby preventing the hose 6 from being entangled and affecting its conveying efficiency.

[0036] Working principle and usage process of the present utility model: During use, first, the battery is clamped and positioned by the clamping seat 4. Then, the clamping seat 4 is driven by the adjusting frame 2 to adjust the tab to the required welding position. When welding by laser excitation, the battery is connected to the tab. Then, the blower 5 is started to convey air into the interior of the hose 6. Next, the hose 6 conveys the gas into the interior of the cooling cover 7. The cooling cover 7 can blow and dissipate heat from the welding part of the tab, thereby achieving the effect of the cooling function, and further improving the welding efficiency of the tab. When the user needs to adjust the position of the cooling cover 7, the servo motor 111 is started to drive the reciprocating screw 114 to rotate. Then, the reciprocating screw 114 drives the adjusting block 9 to adjust the position of the mounting plate 10, so as to facilitate the adjustment of the cooling cover 7 inside the mounting plate 10 to the precise required position. Then, the slide bar 122 is fixed by the fixing plate 121. The spring 124 on the surface of the slide bar 122 pushes the limiting plate 123 to move inward, so that the inner side of the limiting plate 123 fits with the outer side of the cooling cover 7, thereby being able to limit the position of the cooling cover 7 and prevent the cooling cover 7 from shaking during cooling. Moreover, the protection net 132 is fixed to the protection frame 131 by the cooling cover 7, thereby preventing welding residues from splashing into the interior of the cooling cover 7 and causing blockage.

[0037] In summary: For this laser welding fixture for battery tabs, by setting the blower 5, the hose 6 and the cooling cover 7, the gas generated by the blower 5 can be effectively conveyed into the interior of the hose 6, and the hose 6 conveys the gas to the cooling cover 7 and blows the welding part, thereby being able to cool the welded tabs. This solves the problem that the device does not have a cooling structure, resulting in the surface temperature of the tabs being too high and unable to be effectively cooled after the laser welding process of the tabs is completed, thereby reducing the welding efficiency of the battery tabs.
